Bombs for Ukrainian heavy drones are improvised using empty 155 mm artillery propellant charge casings. ZTP delay fuze with an igniter and detonator is placed into a hole in the casing. Gunpowder is poured in, and with a 200 g TNT charge will produce a 0.6–0.7 TNT equivalent. 1/

The Russians are extracting white phosphorus from a 120mm D-5 mortar shell for use with incendiary drone munitions. After cutting the casing with a grinder, it is split open in a water bath because the phosphorus spontaneously ignites on contact with the oxygen in air. 1/

Another Israeli Merkava Mk.4 tank equipped with the Trophy active protection system (APS) is struck by a Hezbollah FPV, which hit the autoloader right next to the system's deployed kinetic launcher. The exposed launcher implies that the system was active—and yet it failed.

A Soviet underwater nuclear test (depth 10 meters) off Novaya Zemlya of the 3.5 kiloton RDS-9 fission warhead on a T-5 torpedo. 30 ships were positioned from 300 m to 1.5 km away. On board the ships were 500 goats and sheep, and 100 dogs. Only the closest ship, a destroyer, sank.
